Abstract: A wheeled toy utilizes a pair of wheels mounted on an axle and moveable by an attached broom handle. A wire support straddles the two wheels, fitting over the outer ends of the axle, and a string assembly attached to the wire support facilitates a turning of the wheels relative to the handle. A fan spindle is rotatably attached to a plastic ball centered between the wheels, and a length of cord may be utilized to spin a plurality of radially mounted balls on the spindle. Alternatively, fan blades of various configurations can be used to rotate the spindle. The fan assembly includes colored rubber balls which orbit around the spindle, and one of the embodiments of the invention includes removable air scoops attachable to one or more balls so as to effectively operate as fan blades.
Abstract: The present invention relates to a means for preventing unnecessary expense in operation of a heating, ventilation and air conditioning system (HVAC) especially in areas wherein occupancy may be sporadic and where the occupants of such areas may not be personally concerned with keeping the expense of running such systems at a minimum. To accomplish this the present invention provides for at least two thermostatic controls within such area, one of such controls having fixed limits for the ambient temperature within the area while the other has variable limits therefor. The fixed limit control is locked and only accessible for adjustment by authorized personnel having the key to such lock. The variable limit control is actuated to override the fixed limit control through the operation of relay switches initiated by an infrared motion sensor unit positioned within such area.
